Description

Technical Field

[0001] This utility model relates to the field of centrifuge feeding technology, and in particular to a disc centrifuge feeding buffer device. Background Technology

[0002] A disc centrifuge is a vertical, high-speed centrifugal separation device that achieves efficient separation of liquid-liquid-solid three-phase media through centrifugal force. Its core structure consists of a stack of discs within a rotating drum. As the suspension passes through the gaps between the discs, solid particles settle and separate under centrifugal force. It is mainly used for processing suspensions, emulsions, and other difficult-to-separate materials, and is suitable for industries such as mineral oil purification, dairy product defatting, and vegetable oil refining. It can perform both liquid-solid separation (clarification operation) and liquid-liquid separation (separation operation). The existing centrifuge feeding mechanism with quantitative adjustment (announcement number: CN222197370U) drives gears to rotate. In conjunction with the distribution of ball bearings and toothed plates, it controls the rotation of the turntable inside the slide table and adjusts the position of multiple quantitative troughs to facilitate appropriate metering and quantitative feeding to meet different usage requirements. Although it can achieve material screening, after the material is put into the hopper, it is directly sent to the discharge pipe after being screened by the vibrating screen plate. When processing larger particles, they fall quickly due to gravity and enter the centrifuge inlet with a strong impact force, which can easily disrupt the material distribution inside the machine, thereby affecting the centrifugal stability and causing repeated wear on the inlet and internal components. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding buffer device for a disc centrifuge.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A feeding buffer device for a disc centrifuge includes a support frame and a conveyor box. A material box is fixed at the top of the conveyor box. Two sets of rotating shafts are fixedly installed inside the material box. Each set of rotating shafts is movably equipped with a material distribution tooth plate. A spring is installed between the material distribution tooth plate and the inner wall of the material box. Two sets of protruding rods are fixed in the middle section of the bottom of the material distribution tooth plate. An installation frame is provided below the material distribution tooth plate. A screen frame is embedded in the installation frame. An inclined plate is fixedly installed inside the conveyor box. Multiple sets of rubber partitions are fixedly installed at the upper end of the inclined plate.

[0005] As a further embodiment of this utility model, the bottom end of the conveyor box is provided with multiple sets of discharge pipes, and each set of adjacent rubber partitions is provided with a discharge port, and the position of each set of discharge ports corresponds to the position of the discharge pipes.

[0006] As a further embodiment of this utility model, each set of discharge pipes is equipped with a valve, and the bottom end of the support frame is equipped with four sets of casters by fasteners.

[0007] As a further embodiment of this utility model, a rubber gasket is fixed between the mounting frame and the inner wall of the material box, and the screen frames are evenly distributed on the mounting frame.

[0008] As a further embodiment of this utility model, the two ends of the spring are respectively fixedly connected to the top of the material distribution tooth plate and the inner wall of the material box.

[0009] As a further embodiment of this utility model, the conveyor box is bolted to the support frame, and the material distribution toothed plate is connected to the rotating shaft through it.

[0010] As a further embodiment of this invention, the springs are distributed at equal intervals within the material box.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When material impacts the distribution toothed plate, the plate swings along the shaft. Under the spring's reset action, it drives the bottom protrusion to periodically impact the mounting frame, thereby driving the four embedded screen frames to generate high-frequency micro-vibrations. At the same time, the sharp tooth structure of the distribution toothed plate disperses the material into multiple fine streams, allowing them to fall evenly into the corresponding screen frames. During the dispersion process, the material can be screened through the screen frames. The qualified material first impacts the rubber baffles inside the conveyor box, absorbing the impact energy with the elasticity of the rubber baffles. Then, it slides smoothly down the inclined path of the inclined plate. By extending the path, the frictional resistance is increased, further slowing down the flow rate. Finally, it is discharged through the discharge pipe at the end of the conveyor box, ensuring the uniformity of feeding into the disc centrifuge while reducing the impact of the material on the centrifuge components.

[0017] Reference Figures 1-5 A feeding buffer device for a disc centrifuge includes a support frame 1 and a conveying box 3. A material box 2 is fixed at the top of the conveying box 3. Two sets of rotating shafts 202 are fixedly installed inside the material box 2. Each set of rotating shafts 202 is movably equipped with a distributing toothed plate 201. A spring 204 is installed between the distributing toothed plate 201 and the inner wall of the material box 2. Two sets of protruding rods 203 are fixed in the middle section of the bottom of the distributing toothed plate 201. An installation frame 5 is provided below the distributing toothed plate 201. A screen frame 501 is embedded in the installation frame 5. An inclined plate 4 is fixedly installed inside the conveying box 3. Multiple sets of rubber partitions 401 are fixedly installed at the upper end of the inclined plate 4.

[0018] Move the entire device to the feed inlet of the disc centrifuge and secure it, ensuring that the discharge pipe 302 at the end of the conveyor box 3 is precisely aligned with the centrifuge feed inlet. The material then enters the feed box 2 and impacts the distributing toothed plate 201 during its descent. Upon impact, the distributing toothed plate 201 swings downwards around the rotating shaft 202, stretching the spring 204. When the spring 204 returns to its original position, the distributing toothed plate 201 quickly rebounds, causing the protruding rod 203 to repeatedly strike the mounting frame 5. Since the mounting frame 5 is elastically connected to the inner wall of the feed box 2 via rubber gaskets 502, the impact force drives the four sets of screen frames 501 embedded in the mounting frame 5 to generate high-frequency micro-vibrations. Simultaneously, the sharp teeth of the distributing toothed plate 201 disperse the material... The material is dispersed into multiple fine streams and evenly introduced into the corresponding screen frame 501. Unqualified impurities are intercepted by the screen frame 501, while qualified material falls through the screen frame 501 into the conveyor box 3. The material entering the conveyor box 3 first contacts the rubber baffle 401. The rubber baffle 401 absorbs the impact energy through its elasticity and guides the material to the inclined plate 4. The material slides down the inclined path of the inclined plate 4 and finally, the buffered material enters the corresponding discharge pipe 302 through each set of discharge ports 402. At this time, the operator can adjust the valve 301 on the discharge pipe 302 to control the flow rate, so that the material is smoothly conveyed to the feed port of the disc centrifuge. While completing the diversion and screening, the material is buffered and flows, reducing the impact on the centrifuge.

[0019] In this embodiment, the bottom end of the conveying box 3 is connected by multiple sets of discharge pipes 302. Each set of adjacent rubber partitions 401 is provided with a discharge port 402, and each set of discharge ports 402 corresponds to the position of the discharge pipe 302.

[0020] The rubber gasket 502 is installed between the mounting frame 5 and the inner wall of the hopper 2. It can provide elastic support for the mounting frame 5, so that the mounting frame 5 can generate high-frequency micro-vibration when the protruding rod 203 impacts, thereby driving the screen frame 501 to screen. It can also buffer the rigid force generated by the impact.

[0021] In this embodiment, a rubber gasket 502 is fixed between the mounting frame 5 and the inner wall of the material box 2, and the screen frames 501 are evenly distributed on the mounting frame 5.

[0022] The bottom end of the protruding rod 203 is set to be semi-circular, which can change the rigid point contact into arc surface contact when it impacts the mounting frame 5 under the action of the material distribution tooth plate 201, thus avoiding local wear on the mounting frame 5. At the same time, it can make the impact force more evenly transmitted to the mounting frame 5, ensuring that the screen frame 501 stably generates high-frequency micro-vibration.

[0023] In this embodiment, each set of discharge pipes 302 is equipped with a valve 301, and the bottom of the support frame 1 is equipped with four sets of casters 101 by fasteners.

[0024] The pointed tooth structure of the material distribution tooth plate 201 can disperse the material into multiple fine streams and evenly guide them into the screen frame 501.

[0025] In this embodiment, the two ends of the spring 204 are fixedly connected to the top of the material distribution tooth plate 201 and the inner wall of the material box 2, respectively.

[0026] The independent flow channels formed by each set of rubber baffles 401 prevent material mixing, while the inclined design of the inclined plate 4 and the friction of the plate surface further slow down the material flow rate.

[0027] In this embodiment, the conveyor box 3 is bolted to the support frame 1, and the material distribution toothed plate 201 is connected through the rotating shaft 202.

[0028] The rubber baffle 401 absorbs the impact energy when qualified materials fall by its own elasticity, and can also form an independent flow channel to guide the materials to slide smoothly down the inclined plate 4, avoid material mixing and help slow down the flow rate, and provide a buffer for subsequent materials to enter the discharge pipe 302.

[0029] In this embodiment, the springs 204 are evenly distributed in the material box 2.

[0030] Spring 204 provides a restoring force after the material-impacted toothed plate 201 swings, driving the protruding rod 203 to periodically impact the mounting frame 5, thus providing power for the high-frequency micro-vibration of the screen frame 501.

[0031] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: First, with the help of the universal wheels 101 on the support frame 1, the entire device is moved to the feeding point of the disc centrifuge and fixed, ensuring that the discharge pipe 302 at the end of the conveying box 3 is precisely aligned with the centrifuge inlet. Then, the material enters the material box 2 and impacts the distributing tooth plate 201 during the falling process. After being impacted, the distributing tooth plate 201 swings downward around the rotating shaft 202. At this time, the spring 204 is stretched. When the spring 204 returns to its original position, the distributing tooth plate 201 quickly rebounds, thereby driving the protruding rod 203 to hit the mounting frame 5 back and forth. Because the mounting frame 5 is elastically connected to the inner wall of the material box 2 through the rubber gasket 502, the impact... The force drives the four sets of screen frames 501 embedded in the mounting frame 5 to generate high-frequency micro-vibration. At the same time, the sharp teeth of the material distribution tooth plate 201 disperse the material into multiple fine streams, which are evenly introduced into the corresponding screen frames 501. Unqualified impurities are intercepted by the screen frames 501, and qualified materials fall through the screen frames 501 to the conveying box 3. The material entering the conveying box 3 first contacts the rubber partition 401. The rubber partition 401 absorbs the impact energy by elasticity and guides the material to the inclined plate 4. The material slides down the inclined path of the inclined plate 4. Finally, the buffered material enters the corresponding discharge pipe 302 through each set of discharge ports 402. At this time, the operator can adjust the valve 301 on the discharge pipe 302 to control the flow rate, so that the material is smoothly conveyed to the feed port of the disc centrifuge.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
